Any ideas on this error. Core 21 exception - unsupported version number. I got 3 units in a row that immediately failed as BAD_WU

I need more information to answer that question.

Somewhere earlier in your log ... or maybe in a previous log (which is stored in the "logs" history file) there is probably information about a failed attempt to download a new copy of FAHCore_21. Find that segment of your history and post it.

I'm also checking with the project owner to see if something is set wrong in that particular project.

Hi all,

This is my project and I’m sorry for this error. I used newer OpenMM version for new runs in this project and forgot it’s not supported yet on f@h. I just deleted the old files and replace the new ones with right version number. There shouldn’t be any version errors now.

Thanks, glad you got it figured out quickly.

I just received a p14158 and it's using FAHCore_21. While it's technically still available, most projects are now running FAHCore_22 instead of FAHCore_21, I suppose because it has a number of new features. There's really nothing wrong with running either one of them.

I got this project and is failing on my GPU, with rocm opencl drivers.

The rocm drivers are hit or miss from reports here on the forum. Some have got them to work, but it may depend on exact versions used. The AMD proprietary drivers and OpenCL support are still the recommended packages to use.

In my case, I'm only using the OpenCL libraries. I've successfully folded other projects as seen in another post viewtopic.php?f=19&t=34970

I got one of these (3, 8249, 6) on a 1070 on Linux

No problems so far (98%) and right on the money for ppd compared to usual Core22 and IRCC faster than older Core21 units.
